In order to disentangle the physical effects at the origin of transition metal K ‐edge X‐ray magnetic circular dichroism (XMCD) in coordination polymers and quantify small structural distortions from the intensity of these signals, a systematic investigation of Prussian blue analogs as model compounds is being conducted. Here the effects of the temperature and of the external magnetic field are tackled; none of these external parameters modify the shape of the XMCD signal but they both critically modify its intensity. The optimized experimental conditions, as well as a reliable and robust normalization procedure, could thus be determined for the study of the intrinsic parameters. Through an extended discussion on measurements on other XMCD‐dedicated beamlines and for other coordination compounds, we finally provide new transition metal K ‐edge XMCD users with useful information to initiate and successfully carry out their projects.
